Applications and characteristics:
|
 JZ119 is agglutinating conversion catalyst which takes the aluminum oxide as the carrier and the nickel as the active. It applied in natural gas or quality hydrocarbon compound part oxidation producing the ammonia or the methanol synthetic gas. It also can be used in ammonia decomposition system producing the reducibility (hydrogen) and the protection gas (nitrogen).

Requirements for feedstock and poison:
|
1、Sulfur is the major poison for nickel-based catalyst。It is required that sulfur content in feed gas to the reformer tube as low as possible, normally＜0.5ppm，preferably＜0.2ppm。 .
2 .Chlorine and other halogens may poison the catalyst, and it is difficult for the poisoned catalyst to restore its activity. Hence, the lower the chlorine content in feed gas, the better.
3、Arsenic may bring about a permanent deactivation of catalyst, and there should not be any arsenic in feed gas。
4、The steam used should not contain any condensable liquids or chemicals used for treating boiler feed-water besides chlorine and arsenic. |
